Declaration of Conformity
Manufacturer’s name: ADEUNIS R.F.
Manufacturer’s address Parc Technologique PRE ROUX IV
283 rue Louis NEEL
38920 CROLLES - FRANCE
declares that the product if used and installed according to the user guide available on
our web site www.adeunis-rf.com
Product Name: ARF19
Product Number(s): ARF7245A / ARF7242A
is designed to comply with the RTTE Directive 99/5/EC:
EMC: according to the harmonized standard EN 301 489.
Safety: according to the standard EN 60950-1/2001
Radio: according to harmonized standard EN 300-220 covering essential
radio requirements of the RTTE directive.
Notes: - Conformity has been evaluated according to the procedure
described in Annex III of the RTTE directive.
- Receiver class (if applicable): 3.
According to the 1999/519/EC recommendation, minimum distance between the product
and the body could be required depending on the module integration.
Warnings: - CE marking applies only to End Products: Because this equipment is only a
subassembly, conformity testing has been reduced (equipment has been design in
accordance to standards but full testing is impossible). Manufacturer of End Products,
based on such a solution, has to insure full conformity to be able to CE label marking.
- As the integration of a radio module requires wireless technological
knowledge, ADEUNIS RF proposes its technical proficiency to its customers for a pre-
compliance qualification of end products. In case of no-conformity, ADEUNIS RF will not
be held back responsible if this stage has not been realised.

General presentation
The ARF7242A module is a Xtal based reference 869.525MHz – 10mW
ASK transmitter These transmitters are compatible with any ASK
receiver able to handle 100% modulations as the ARF7245A
(description enclosed)
The ARF7245A receiver is a very high sensitivity (0.5µV / -113dBm)
ASK Superheterodyn with single frequency switch module.
It could function with all ASK 100% Xtal based transmitter (bandwidth:
100kHz).
These modules are supplied without antenna. To increase the
performances, we recommend the use of a « Whip » antenna.
All these modules build rough radio links; bit coding and frame coding
have to be managed by an associated digital controller.
They are all available as subassembly daughter boards to complete an
electronic digital motherboard.

Size / Electric pin assignment
- PWRUP: Power up input.
-TX-DATA: Data input.
NOTE
•Dimensions are given in mm
•SMD pads pitch is 2.54 mm.
NOTE
•The interface with the mother board has to be achieved
through copper pads on both PCB sides or with 2 HE13 or HE14 SIL
pins (non supplied). No component can be located under the module
when using SMD mounting.
•Radio module has to be powered using an external power
supply connected between VCC and GND. Operating voltage has to be
in the 2 – 5V range.
•Power is trigged using the PWRUP pin:

ARF19 User Guide
Ref. 05-11-V3-pcy p. 8
•PWRUP = ″1″→Transmitter on.
•PWRUP = ″0″→Transmitter off.
•When in standby mode, “TX-DATA” pin has also to be
logical 0.

Dimensions / Pinning
RESET: Not used. Do not connect.
PWRDN: Standby mode (when 1).
RXDATA: Received data
NOTE
•Dimensions are given in mm
•SMD pads pitch is 2.54 mm.
•PCB thickness: 1,6mm.

NOTE
•Plugged mounting needs a 1.6mm fence in the motherboard.
Electrical connections are made by simple manual or wave soldering on
the soldering face of MB.
•Radio module has to be powered using an external power
supply connected between VCC and GND. Operating voltage has to be
in the 2.2 – 5V range.
•Power is trigged using the PWRDN pin :
- PWRDN = ″1″→Receiver off.
- PWRDN = ″0″→Receiver on.
ATTENTION
If using a pull down resistor on PWRDN, its value has to be less than
220 Ohms!
If the receiver stand-by mode is activated immediately after powering
up the equipment, please use timings below (for good receiver IC
internal Reset).
